Wireless local loop (WLL), is the use of a wireless communications link as the last mile / first mile connection for delivering plain old telephone service (POTS) or Internet access (marketed under the term broadband ) to telecommunications customers. Various types of WLL systems and technologies exist. Other terms for this type of access include Broadband Wireless Access (BWA), Radio In The Loop (RITL), Fixed-Radio Access (FRA), Fixed Wireless Access (FWA) and Metro Wireless (MW).

WLL and FWT are generic terms for radio based telecommunications technologies and the respective devices which can be implemented using a number of different wireless and radio technologies. Wireless local loop services are segmented into a number of broad market and deployment groups. Services are split between licensed – commonly used by carriers and Telcos – and unlicensed services more commonly deployed by home users and Wireless ISPs (WISPs).[citation needed] Licensed points-to-point microwave.
In this dynamic and constantly evolving wireless industry, we’ve accepted the fact that there is no “final” draft in our Wireless Industry Overview or any of our industry overview documents. Instead, we’re always updating these “living” documents. But while the industry keeps changing, as the head of research, I’ve noticed I’m consistently asked the following questions. What does the word “penetration” refer to in the wireless industry? Penetration is the number of active wireless subscriber units divided by the total U.S. and territorial populations (Puerto Rico, Guam, American Samoa, Northern Mariana Islands and the U.S. Virgin Islands). At year-end 2010, 96 percent was the number of active units divided by the total population. Of course, since so many people are now using more than one wireless device (tablet and phone, anyone?), it’s entirely possible for penetration to reach above 100 percent. That doesn’t mean that every single person really has a wireless device, but it does mean that the number of active devices may soon be more than the total population. Stay tuned for the release of our next survey at Enterprise & Applications on October 11! What should consumers do with old cellphones and chargers? Many companies have programs that promote the recycling of old cellphones and other wireless devices. Visit gowirelessgogreen.org to find more information about your carrier’s recycling program. All major carriers and many others will accept any device or accessory at their stores, regardless of which carrier provided your service. Don’t forget to erase your personal information before you make a donation. What do “direct carrier jobs” and “wireless carrier payroll” mean? “Direct carrier jobs” refers to the wireless service providers’ employees, consisting of direct sales employees (full-time sales employees) and other employees (full-time employees including.
